Door with variable length screen

ABSTRACT

An exterior door incorporates at least one moving glass insert or sash slidable in first and second spaced apart tracks. An end of the insert is coupled to an end of a spring biased rolled screen. As the insert moves from the roll, the screen is extracted therefrom providing a continuously variable screened region in the door. The insert can be positioned using a counterbalance or spaced apart latchable locations in the door.

[0001] This application is a utility application claiming the benefit of the earlier filing date of provisional application Serial No. 60/310,557 filed Aug. 7, 2001.

FIELD OF THE INVENTION

[0002] The invention pertains to doors. More particularly, the invention pertains to doors having at least one slidable glass pane or panel with an extendable screen attached thereto.

BACKGROUND OF THE INVENTION

[0003] Storm doors which incorporate panes of glass and screens are known. Some forms of such doors include screens which are fixedly mounted to the frame of the door with sliding glass inserts. With these doors, the inserts usually can be locked into a plurality of vertical positions with spring loaded latches to expose varying degrees of screen. When the inserts are moved to their fully close position, such as during storms or in cold weather, a person looking at the door, must look through at least one pane of glass and the screen.

[0004] In other forms of doors, glass inserts or screen inserts are installed on the doors' frame depending on the season. In warmer weather the glass insert is removed and a screen insert is used in the frame. In cooler weather, the screen is removed and a glass insert is attached to the frame. With such doors, an individual looking at the door looks through either a pane of glass or a screen but not both.

[0005] One known door configuration provides a fixed screen with a counterbalanced insert. In this configuration, the insert is not latched at a selected position on its track. The counterbalance makes it possible to position the insert at any desired position o the track. However, when the insert is in its closed position, a person viewing the door must look through both the glass insert and the screen.

[0006] Patio door configurations are known which include sliding glass doors which can be opened or closed to provide access to a patio or a porch. Spring biased screen modules are known which can be attached to the patio door frame. These modules include horizontally retractable screens which can be extended across a patio door opening to exclude insects or other flying pests.

[0007] While the known doors are generally suitable for their intended purpose, they all suffer from one or more deficiencies in performance, convenience and ease of use. There continues to be a need for multi-season doors which provide convenient and easy to use screened openings during warmer drier weather while at the same time making it possible to easily close the screened area with a glass pane during cooler or wetter weather. Preferably such doors could be manufactured, at least in part, using techniques for manufacturing existing doors so as to benefit from the economies of scale that such manufacturing capabilities provide. Additionally, it would be preferable if such doors were easy to maintain and designed to be forgiving in the event that the screen is in need of replacement.

[0008] Numerous other advantages and features of the present invention will become readily apparent from the following detailed description of the invention and the embodiments thereof, from the claims and from the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0032] While this invention is susceptible of embodiment in many different forms, there are shown in the drawing and will be described herein in detail specific embodiments thereof with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to the specific embodiments illustrated.

[0033] In one embodiment of the invention, an exterior door incorporates a replaceable screen module which includes an integral, spring biased, retractable screen which is coupled to a movable glass insert in the door. As the insert is moved from the screen, the screen is withdrawn from its retracted position and extends along the frame of the door screening the otherwise open region from which the glass insert has moved. As the window sash or insert moves in the opposite direction toward the screen module, the screen is retracted into the module reducing the ventilation region available in the door.

[0034] FIGS. 1A-1C illustrate various views of a door 10 which embodies the present invention. The door 10 includes a header 12 a, two door jambs 12 b, c and a sill 12 d. The members 12 a . . . d define a door frame with an interior region which in the door 10 includes a kick plate generally indicated at 14 a, a lower pane or glass insert 14 b, and an upper pane or glass insert 14 c. Mullions 18 a, b on the exterior side of the frame join jambs 12 b, c.

[0035] In the door 10, the pane or insert 14 b is fixedly mounted between the jambs 12 b, c and above the kick plate 14 a. The pane or insert 14 c is mounted in tracks, discussed in more detail subsequently, for vertical motion generally in directions 16 a, b relatively to insert 14 b.

[0036] When the insert 14 c is positioned at its uppermost location adjacent to header 12 a, the door 10 is fully closed with two glass panes as one would use it in cool or wet weather. The pane or insert 14 c can be moved, vertically, in direction 16 b, away from header 12 a thereby opening the upper portion of door 10 for ventilation.

[0037] A screen module 20, best seen in FIG. 7A can be coupled to the jambs 12 b, c, header 12 a or sill 12 d. Module 20 carries a retracted screen which has a free end which carries an attachment member 22 which is coupled to an upper end of insert 14 c. As the insert 14 c is moved in the direction 16 b, screen fabric or material 22-1 from the module 20 is extracted therefrom filling any gap or space between an upper end of insert 14 c and header 12 a.

[0038] Door 10 can thus, as described above, be converted from a storm door with two glass panes to a screen door simply by moving pane or insert 14 c vertically downwardly. Where insert 14 c is moved vertically downwardly to kick plate 14 a, the extracted screen fills the entire area previously closed by pane 14 c.

[0039] When the insert 14 c is raised, direction 16 a, the screen material 22-1 retracts into module 20 for storage. As discussed below, module 20 is removable for maintenance or replacement.

[0040] It will be understood that alternate configurations to the door 10 come within the spirit and scope of the present invention. For example, the screen module 20 can be mounted at or near the base 12 d to provide an openable lower screened region. Alternately, instead of screening material, sheet plastic could be used in the module 20.

[0041] Members 12 a-12 d of the frame for the door 10 can be formed of metal, such as extruded aluminum, extruded or molded plastic, or partly or completely of a wood product. Inserts 14 b, c need not include glass but could in fact be closed with translucent or transparent plastic material without departing from the spirit and scope of the present invention.

[0042]FIG. 2A is a rear elevational view of the door 10 illustrating the location of screen module 20 adjacent to header 12 a. Screen module 20 is enclosed by a removable cover 24 which can be removed for purposes of maintenance and for replacing the module 20.

[0043]FIG. 2B illustrates an alternate embodiment, a wood core door 10-1 which incorporates screen module 20. The wood core door 10-1 can be formed with a wood-products core covered with either metal, such as aluminum, or cured resin such as vinyl. It will be understood that the screen module 20 is coupled to a sash or insert, comparable to the insert 14 c, which moves vertically in tracks, as would be understood by those of skill, in the frame for the door 10-1.

[0044]FIGS. 3A and 3B are an exploded view of the door 10 and a rear isometric view thereof.

[0045] As illustrated in FIG. 3A, module 20 incorporates a spring or retractor assembly 26 which is carried in a hollow screen roll or cylinder 28. The cylinder 28 rotates about retractor assembly 26 and pivot cap 28-1.

[0046] The module 20 is attached to the door so as to permit rotary motion thereof by brackets 30-1 and 30-2, best seen in FIGS. 7A-C. Screen roll 28 carries the coiled screen fabric 22-1 with attached connection member 22, best seen in FIG. 7B.

[0047] The spring assembly 26 exerts a substantially constant retracting force on the spring fabric on the roll 28 as the insert 14 c is moved vertically in directions 16 a, b. The screen material 22-1 is thus constantly under tension.

[0048] The insert 14 c in door 10, is counterbalanced by counterbalancing mechanisms 36 a, b carried by the insert 12 a. The counterbalancing mechanisms 36 a, b move with the insert 14 a in the jambs 12 b, c and are invisible to the user. Types of counterbalances include block and tackle balance, spiral balance and coil spring balance.

[0049] The counterbalances 36 a, b make it possible to smoothly move the insert 14 c in the direction 16 a, b. The insert 14 c can be positioned anywhere along its range of travel and will remain there until moved due to the forces exerted by the counterbalance mechanisms 36 a, b.

[0050]FIGS. 4A, B illustrate an alternate embodiment, a door 10-2, which embodies the present invention. Those elements of door 10-2 which correspond to previously discussed elements of the door 10 have been assigned the same identification numerals. As an alternate to the counterbalance mechanisms 36 a, b, the door 10-2 incorporates spring biased finger operable latches 38 a, b which are carried by the insert 14 c′. The latches extend laterally outwardly into slots in the jambs 12 b′, c′ to lock the insert 14 c′ into a plurality of spaced apart vertical positions.

[0051] In the door 10-2, the insert 14 c′ can be moved vertically to a locking position, the movement will retract the screen 22-1 off of the roll 28 and filling the area of the door frame from which the insert 14 c′ has been moved. The mechanical latches 38 a, b will lock the insert 14 c′ at the desired degree of openness in the frame of the door 10-2 desired.

[0052] In yet another embodiment, insert 14 c can frictionally engage tracks in jambs 23 b, c. The frictional forces will support insert 14 c at any one of a variety of positions. In this embodiment, no counterbalances or latches are needed.

[0053]FIGS. 5A and 5B are sectional views taken along plane 5A-5A of FIG. 1A. The views of FIGS. 5A, B illustrate the relationship of various structural elements of the door 10 as the insert 14 c moves from a fully closed position, FIG. 5A, to a partially open position, FIG. 5B. FIG. 5B illustrates the extended screen fabric 22-1.

[0054]FIG. 5C, a section taken along plane 5C-5C of FIG. 1A illustrates the insert tracks 52 b, 52 c which run axially along each of the jambs 12 b, c. The insert 14 c moves axially in and is retained within those tracks.

[0055] As illustrated in FIG. 5B, the insert 14 c which is coupled to the screen fabric 22-1 moves axially in tracks 52 b, c between insert 14 b and mullion 18 a. The screen end retaining member 22 is slidably received in a retaining feature 50 located at an upper end of the insert 14 c.

[0056] Edges of the screen fabric 22-1 are confined in axial tracks 54-1, -2. These can be formed in jambs 12 b, c.

[0057]FIG. 5D illustrates the counterbalance mechanism 36 a, b which is carried by the insert 14 c. Hence, insert 14 c can be located at any vertical position on its range of travel as defined by the tracks 52 b, 52 c along the jambs 12 b, c. When so positioned, the screen fabric 22-1, will be extended from the module 20 to the connector feature 50 to close the opening in the frame of the door 10 left by moving the insert 14 c to a position closer to the kick plate 14 a.

[0058]FIG. 5D also illustrates the screen material 22-1, illustrated in phantom, extended, as in FIG. 5B, extending between first and second weather stripping elements 54 a and 54 b. Weather stripping element 54 a extends axially along the respective jamb 12 b, c on each side of the door 10. The weather stripping 54 a can be any form of weather stripping as would be known to those of skill in the art.

[0059] The weather stripping 54 b is different and unlike the weather stripping 54 a. The weather stripping 54 b is also positioned in an axially oriented slot which runs along the jambs 12 b, c.

[0060] Weather stripping 54 b is commercially available from Reddiplex Group PLC, Worchestershire, England under the trade name “MESHLOCK” and is formed with a mounting section 56-1 which slidably engages the respective slot in the jamb 12 b, c. The mounting section 56-1 carries a deflectable planar element 56-2 which extends from the mounting section 56-1 toward the weather stripping 54 a at a predetermined angle in a range of 15-75° relative to the plane of the screen.

[0061] The weather stripping 54 a acts to press the edge of the screen material 221 toward the MESHLOCK-type weather stripping 54 b, see FIG. 5F. This interaction provides a screen edge retention function. The fibers of the MESHLOCK weather stripping 54 b resist screen material 22-1 being pulled from between weather stripping 54 a, b, and the tracks 54-1, -2.

[0062] It will be understood that other commercially available forms of weather stripping can be used instead of the MESHLOCK brand without departing from the spirit and scope of the invention.

[0063] It will be understood that while the MESHLOCK weather strip 54 b has been illustrated in FIGS. 5D and 5F as exhibiting an acute angle between the mounting section 56-1 and the screen retaining section 56-2, other variations of MESHLOCK weather stripping could be used. Alternately as in FIG. 5C, the members 56-1′, -2′ could be oriented at 90° to one another. In this embodiment, the track in which the mounting section 56-1′ would be located would be oriented at an appropriate angle, best seen in FIG. 5G, relative to the respective jamb 12 b, c to provide the desired interaction of pressing the screen material 22-1 between the weather stripping 54 a, 54 b′.

[0064]FIGS. 6A, B and C taken together illustrate screen fabric or cloth 22-1 slidably engaging track 54-1, similarly 54-2, located in each of the jambs 12 b, c and which extend axially along the jamb. The end attachment feature 22 also slidably engages the track or slot 54-1, -2 on each of the jambs 12 b, c.

[0065] Though the screen cloth or material 22-1 may be forced out of the respective tracks 54-1, -2 in each of jambs by a laterally directed force, the screen attachment member 22 will continue to remain in each of the tracks. This is facilitated by the shape of the attachment member 22 which includes an end region 23 which extends into the respective slot 54-1, -2.

[0066] In this instance, assuming that the screen cloth 22-1 has been forced from the respective track 54-1, the upper insert 14 c can be moved to its fully closed position adjacent to header 12 a to retract the screen onto the screen roll 28. In this circumstance, the attachment feature 22 is properly aligned to re-enter the tracks 54-1. As the insert 14 c is moved away from the header 12 a, it will pull the attachment member 22 with it. The ends 23 of the attachment member 22 will enter the respective slots 54-1 pulling the screen cloth 22-1 with them and retracking the screen. Alternately, the attachment member 22 can exhibit a retracted condition, adjacent to the screen module 20 while continuing to remain in the tracks 54-1.

[0067] Thus, as described above, if a force is exerted against the screen material 22-1 to pull it out of the side tracks 54-1 in each jamb, it is only necessary to reclose the insert 14 c to rewind the screen material 22-1 into a proper configuration so that it will be immediately re-extendable into the slots or tracks 54-1.

[0068]FIGS. 7A, 7B and 7C illustrate additional details of the screen module 20. The module 20 is supported adjacent to the header 12 a by brackets 30-1, -2. Module 20 can be removably attached to the header, the sill or the jambs. The module 20 is removable from the brackets 30-1, -2 for maintenance and/or replacement once the cover 24 has been removed from the respective door.

[0069]FIG. 8 illustrates additional details of removing and replacing the module 20. The connecting member 22 can be slid from the retaining feature 50 of the insert 14 c as illustrated in FIGS. 8 and 9. When so-slid from the retaining feature 50, the entire module 20 can be replaced. Replacement involves attaching the connecting member of the new module to the attachment feature 50 by reversing the process illustrated in FIGS. 8 and 9. The screen roll 28 and screen fabric 22-1 can then be reattached brackets such as brackets 30-1, -2 in the header of the respective door. The cover 24 can be replaced. Moving the insert 14 c vertically toward and away from the header will cause the screen fabric 22-1 of the replacement module to retract and extend as expected.

[0070]FIGS. 10, 10A and 10B illustrate a door 60 which has a header 62 a, jambs 62 b, c and a sill 62 d. The door 60 includes insert 64 a which is movable vertically toward the header 62 a and away therefrom toward the sill 62 d. The insert 64 a can be supported by counterbalances, latches or frictional forces as discussed above relative to the door 10.

[0071] The door 60 carries a screen module 66, best illustrated in FIG. 10A. A free end of the screen of the screen module 66 is coupled to an upper end of insert 64 a as discussed above.

[0072] A lower panel 64 b of the door 60 is hollow and contains a space into which the insert 64 a can be stored as it is moved downwardly toward the sill 62 d. In this configuration, where the insert 64 a is partly open, a portion of the screen 66 a extends from the screen module 66 and fills the open space between jambs 62 b,c and header 62 a. The remainder of the space between the jambs 62 b, c is filled by a portion of the insert 64 a and the panel 64 b. Thus, the door 60 provides convenient out of sight storage for the insert 64 a.

[0073]FIG. 11 illustrates a plurality of alternate coupling members 50-1 . . . 50-6 that could be carried on the movable insert or pane, such as the insert 14 c, and couplable to a free end of the screen fabric 22-1. As illustrated in FIG. 11, in each instance, the free end of the screen 22-1 would include a coupling element, such as 22-2 . . . 22-7 which would slidably engage the respective coupling member 501 . . . 50-6.

[0074] It will be understood that other arrangements can be used to attach a free end of the screen member 22-1 to a moving insert or pane. Alternates or include a spline which would trap the free end of the screen fabric 22-1 in contact with the movable inserts such as 14 c clamps or adhesives. Other variations come within the spirit and scope of the invention.

[0075]FIG. 12 illustrates a door 80 which incorporates a screen module 82, of the type discussed previously, which can be attached to door 84 as an after the fact accessory or add-on. The module screen 82 can be attached to the door 84 by fasteners 86 in the vicinity of the header 84-1 of the door.

[0076] The screen fabric 82-1 can be pulled from the module 82 to close an opening in the door created by moving insert 86 downwardly away from the module 82. A free end 82-2 of the screen material 82-1 is attached to the sash or insert 86. Attachment can be effected by any of the previously discussed methods including using a spline, adhesive, providing attachment clips which slidably engage a portion of the sash of the insert 86. Other attachment vehicles can be used to connect the free end 82-2 to an upper end of the insert or sash 86 without departing from the spirit and scope of the present invention.

[0077] As the sash or insert 86 is moved toward the screen module 82, the fabric 82-1 rollably retracts into the module 82 as a result of the internal spring mechanism, discussed above, in connection with door 10. The screen material 82-1, also as discussed above, is under a constant pulling force due to the spring biasing mechanism of the module 82 which continually attempts to retract the fabric 82-1 into the module 82. Thus, as the sash or insert 86 moves toward the module 82, the screen material 82-1 is immediately rolled into the module 82 for out of the way storage.

[0078] It will also be understood that a resin or plastic sheet could be used as an alternate to screen fabric 82-1 without departing from the spirit and scope of the present invention. Thus, the screen module 82 provides a mechanism for adding to any existing door, after installation, a retractable screen feature such that existing screen panels or inserts in the door can be removed. This improves convenience and visibility in that with the sash or insert 86 closed, the screen fabric 82-1 is completely retracted and an individual looking at the door looks directly through the glass inserts or sashes without having to look through a screen.

[0079] From the foregoing, it will be observed that numerous variations and modifications may be effected without departing from the spirit and scope of the invention. It is to be understood that no limitation with respect to the specific apparatus illustrated herein is intended or should be inferred. It is, of course, intended to cover by the appended claims all such modifications as fall within the scope of the claims.
